Ok thanks guys i will look into the smeller one! But now my teacher is saying i have to find one that runs off a 18m or o8m pickaxe? Is that possible i think he is reluctant to use an Arduino because he hasn't before( Me either) But all the cubes i see are on arduino's??
I have no idea what the difference between the two are!
Are arduinos difficult to use they just seem to be the one that everybody uses?
